Sika® Plastiment® SD-6 BH

Semi-dry precast concrete admixture

Sika® Plastiment® SD-6 BH is a liquid admixture, based on a blend of synthetic and refined natural materials, which improves compaction and hydration of semi-dry concrete mixtures.
Suitable for use in tropical and hot climatic conditions.

Sika® Plastiment® SD-6 BH provides the following:
  • Efficient cement dispersion and hydration permitting maximum economy
  • Increased 24 hour and 28 day strengths
  • Less damages due to early age handling
  • Vibration and compaction are more efficient leading to consequent reductions in equipment wear
  • Increased density
  • Reduced permeability
  • Improved waterproofing
  • Reduction / elimination of efflorescence
  • Better surface finish
  • Improved visual quality

Technical Information

Concreting Guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® Plastiment® SD-6 BH in concrete. Refer to relevant standards.
Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Concrete Mix Design

Retain normal water quantities, but reduce the cement content by 5 - 10 %

Application

Application Information

Dispensing

Sika® Plastiment® SD-6 BH is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant.
Do not add Sika® Plastiment® SD-6 BH directly to the dry mix.
For optimum utilization we recommend thorough mixing at a minimum wet mixing time of 60 seconds.
Consumption

Recommended Dosage

0.2 - 0.5 % by weight of binder.
Trial mixes must be performed to establish the exact dosage rate required for the mix design, raw materials and climatic conditions.
